Bump map not applying at all
You should really plug your normal map into both the Diffuse and Glossy node, however, that's not why you are seeing no effect.

The normal map you are using is basically flat. You can see this by looking at it in the UV Image Editor. It's from a glossy surface with virtually no variations in surface depth. You will simply not see much, if any, effect from that normal map.

To contrast, look at the normal map you are using (basically all one colour) and then look at this (randomly selected) one I found on Google from a brick surface that has a lot of variation: http://jsoverson.github.io/texture.js/demo/images/brickwork-normal.jpg
